Experts buy three tips for farmers to buy fertilizer

"A crop of flowers, all rely on fat to become a home." At the moment is the spring season, busy buying high-quality fertilizer is the minimum wish of the crop people. However, such things as “fat treasure”, “potassium treasure” and “××fere king”, which have a wide variety of names and exaggerated propaganda, have flooded the market, and incidents that infringe on the interests of farmers have occurred. In this regard, how should farmers’ friends go to falsehood? Autonomous regions and Fertilizer chief expert Ma Yulan her 30 years of hands-on, friends of farmers to buy fertilizer given three prompts.

Everlasting

Ma Yulan introduced that although there are many names of various types of chemical fertilizers, they are not only different from their own, but also nitrogen fertilizer, phosphate fertilizer, potash fertilizer, trace element fertilizer, and a large amount of element soluble fertilizer which is produced with micro and drip irrigation technology. The flushing of fertilizer). Common nitrogen fertilizers in Ningxia include urea, ammonium bicarbonate, ammonium nitrate, etc.; phosphate fertilizers have passed calcium phosphate, heavy superphosphate, diammonium phosphate; potassium potassium sulfate, potassium chloride. The trace element fertilizer is mainly zinc fertilizer and potassium dihydrogen phosphate.

In view of the variety of products on the market, the quality and price are uneven. When farmers buy, they first use the packaging mark to falsify the truth. The State Administration of Quality Supervision, Inspection and Quarantine issued GB18382-2001 "fertilizer logo, content and requirements", GB15063-2001 "fertilizer (complex fertilizer)," the two mandatory national standards, was January 1, 2009 and July From the 1st , it will take effect in production and circulation. Manufacturers are required to indicate the national standards, industry standards and the names of fertilizers already specified. For the names of fertilizers with special uses, the names of the fertilizers should be marked with the small No. 1 font, such as “composite fertilizer potassium sulfate type”. If only the trademark or non-standard product name is seen on the package, and the active ingredient content, net weight, standard number, production license number, production date or batch number, manufacturer name and site address are not visible, it is important to not purchase.

The right one is the best

Perhaps the farmer will ask, the quality of the fertilizer I bought is no problem, how can I use the effect is not good? Ma Yulan explained that any fertilizer has applicability to crops. Some fertilizers are suitable for the south but not for Ningxia. They are suitable for mountainous areas but not for Sichuan. Some fertilizers are suitable for food crops but not for economic crops.

“A case of “Yangyangtian” brand compound fertilizer produced by a distributor in the spring broadcast site will be taken as an example. Regardless of its nitrogen, phosphorus and potassium, it has 14% , 15% and 16% respectively , especially the highest potassium content. For the soil with high potassium content in Ningxia, excessive application will be counterproductive.” She said that nitrogen fertilizer and phosphate fertilizer will encounter similar problems in some soils, which will not only improve crop yield and quality, but will harden the soil and cause surrounding The surface pollution of the water body has the phenomenon of “water bloom” on the lake surface or “red tide” in the offshore waters . Therefore, she believes that the purchase of fertilizer, only to buy the right is the best.

What is appropriate? the answer is--

The most scientific fertilization according to the side

With the promotion of formula fertilization, the use of fertilizer formula farmers more and more, last year, the application rate of fertilizer formula Ningxia reached over 40,000 tons, but in order to save some farmers, especially farmers in mountainous areas, the use of mu minus Half, reducing the rate of technology in place, coupled with too much formula fertilizer on the market, has discouraged many farmers.

To this end, Ma Yulan suggested that farmers in Ningxia should select products produced by eight fixed-point formula fertilizer enterprises in the region , because it is based on a large number of sampling and analysis analysis by Ningxia technical department, and then through field trials and demonstrations, for different regions and crops in the region. The production level and other factors are tailor-made and have strong pertinence. Although some formula fertilizers produced in large quantities in the field are cheap, the formula is based on the results of the soil testing in other provinces. If you purchase the formula fertilizer in the field, it is difficult to have the desired effect. The method of saving money and rest assured is to purchase high-quality single fertilizer according to the fertilization recommendation card provided by the local agricultural technology department, and mix it into a formula fertilizer suitable for home use, which is more scientific to use.
